95% of Our Tap Water Contains Lead & Microplastics

More than 95% of U.S. water systems contain at least one cancer-linked contaminant above health-based recommendations. Federal regulations allow toxin levels that are often 10 to 100 times higher than what independent health experts consider safe.


Our Water Infrastructure is Crumbling

Over 9 million lead service lines still deliver drinking water to U.S. homes today.

Most of the country’s water infrastructure is over 100 years old, corroded, and leaching toxic metals.

Perfect water filter

The newest model of the Opti water filter is flawless. The water is delicious, the basin is large and functional, and it fits in a fridge that does not have tall spaces between shelves. Great customer service too. 10/10

No More Bottled Water

I love Opti water filter. It gives me peace of mind knowing I will have clean, filtered water all the time. It also saves my back from lifting the heavy bottled water while saving the environment from plastic bottles.

POINT OF USE FILTRATION

Smart Filtration for Everyday Wellness

Unlike under-sink or whole-home systems, Opti Water™ uses true point-of-use filtration — purifying water at the exact moment it’s dispensed. Other systems may clean water at the source, but it still travels through pipes, faucets, and fixtures where it can pick up new contaminants. Opti ensures your water is filtered at the final stage — the moment it enters your glass — for maximum purity and peace of mind.

MAXIMUM CONTAMINANT EXTRACTION

Fast Water is Easy. Clean Water Takes Time.

While other filters prioritize speed, our filters use tightly packed organic compounds like coconut husk carbon to slow the flow just enough to maximize contact time and filtration efficiency. That means more contaminants removed and fewer toxins in your glass, making your water safe for the whole family to enjoy.

From the Opti Water™ Community

Powerful Filtration You Can Taste & Trust

Unlike most competitors, Opti Water™ uses solid compressed carbon filtration — not loose granules — for deeper, more efficient contaminant removal. This means better performance, longer filter life, and cleaner water in every drop.
